【摘要】：以人口空间分布及其与资源环境和社会经济协调性评价为核心,提出了一整套人口与资源环境和经济社会发展协调水平评价的指标体系与模型方法;以分县为基本单元,定量评价了2010年中国人口与资源环境和社会经济发展的协调性和协调程度;根据人口分布适宜度高低和限制性差别,划分了中国分县人口分布适宜等级和限制类型,定量揭示了中国不同地区人口与资源环境和社会经济协调发展的时空格局和地域特征。研究表明:①2010年中国有3/5以上的县(市、区)人口分布与人居环境基本适宜,中国分县人口分布与人居环境自然适宜性保持了高度一致性;②2010年中国有1/2以上的县(市、区)人口发展基本不受水土资源约束,分县人口分布与水土资源适宜性处于中等水平;③2010年中国有超3/5的县(市、区)人口与社会经济发展基本协调,人口分布的社会经济协调性良好;④2010年中国近3/5的县(市、区)人口分布适宜度在60以上,人口资源环境与发展处于基本协调或相对协调状态;⑤2010年中国分县人口资源环境与发展的协调程度东部优于中部、中部优于西部;⑥2010年中国分县人口分布适宜度可划分为人口资源环境与发展基本协调、相对协调、有待协调和亟待协调4个适宜等级与10个限制类型。
[Abstract]:Based on the evaluation of population spatial distribution and its coordination with resources, environment and social economy, this paper puts forward a set of index system and model method for evaluating the coordinated level of population and resource environment and economic and social development. The coordination and coordination degree of population, resources, environment and social and economic development in China in 2010 are quantitatively evaluated, and the appropriate grades and restricted types of population distribution in different counties of China are classified according to the suitability and restrictive differences of population distribution. The spatial and temporal patterns and regional characteristics of the coordinated development of population, resources, environment and social economy in different regions of China are revealed quantitatively. The results show that: 1 in 2010, there were more than 3/5 counties (cities and districts) in China, which were basically suitable for population distribution and human settlement environment. The population distribution in different counties in China has maintained a high degree of consistency with the natural suitability of human settlements. (2) in 2010, more than 1/2 counties (cities and districts) in China had population development that was basically independent of the constraints of water and soil resources. The population distribution and the suitability of soil and water resources are at a medium level by county level; 3The population and socio-economic development of more than 3/5 counties (cities and districts) in China are basically coordinated in 2010, and the social and economic coordination of population distribution is good; in 2010, nearly 3/5 counties (cities) in China, The suitability of population distribution is above 60, and the population, resources, environment and development are basically coordinated or relatively coordinated; 5The eastern part of China's population, resources, environment and development in 2010 is superior to the central region in terms of coordination of population, resources, environment and development. The suitable degree of population distribution in different counties of China in 2010 can be divided into basic coordination of population resources, environment and development, relative coordination, and need to be coordinated and urgent need to coordinate 4 appropriate grades and 10 restricted types.
